Comprehensive Guide to Corporate Sustainability Reporting Directive (CSRD)

What is CSRD?

The Corporate Sustainability Reporting Directive (CSRD) is a major step forward in standardizing sustainability reporting within the European Union. Building on the Non-Financial Reporting Directive (NFRD), the CSRD aims to enhance transparency by requiring companies to disclose structured and verifiable environmental, social, and governance (ESG) data.

However, the Omnibus proposal, introduced in 2025, has significantly altered some aspects of CSRD compliance. These updates are aimed at reducing administrative burdens and focusing on larger companies with substantial economic impact. This guide will help you navigate the latest changes and prepare for compliance.

Key Changes from the Omnibus Proposal (2025 Updates)

Note: In February 2025, the European Commission proposed several changes to the CSRD to simplify reporting requirements. These changes are currently pending approval.

1. Updated scope of companies required to report

2. Postponed reporting deadlines

The original reporting deadlines have been pushed back:

3. Clarified assurance requirements

Limited assurance remains the primary requirement for now, with the European Commission planning to issue targeted guidelines by 2026.

4. Sector-specific reporting requirements removed

The Omnibus proposal eliminates sector-specific sustainability reporting obligations, reducing compliance complexity.

5. Introduction of digital-first reporting

All CSRD reports must be machine-readable and tagged in XHTML format, making them easily accessible for investors and regulators.

CSRD Reporting Requirements and Compliance Timeline

The CSRD Report: Structure and Best Practices with AI-Powered Software

Given the complexity of CSRD reporting, companies are increasingly turning to AI-powered software solutions to streamline compliance. Below are best practices and how you can get your CSRD report done with Karomia.

Step 1: Upload your materiality results

If you've conducted your assessment through the Karomia platform, select the relevant assessment from the dropdown menu. This ensures maximum detail and structured data for generating your CSRD report.

If you conducted your double materiality assessment outside the Karomia platform, you’ll be prompted to select all subtopics identified as material. Externally conducted assessments may require additional validation to ensure consistency with CSRD standards. Karomia’s platform streamlines this process by structuring and aligning inputs with regulatory requirements.

Step 2: Upload your ESG documents

To maximize data prefilled by Karomia AI, upload all relevant ESG documents, including:

Avoid uploading outdated, duplicate, or irrelevant files, as this can lead to inefficiencies in AI analysis and increase manual review time.

Upload your ESG documents

Step 3: Review the AI output and complete your report

Based on the uploaded data, Karomia AI generates initial answers for your report scope, flags missing data, and suggests disclosures. This is commonly known as the Gap Assessment. However, with Karomia, this step is seamlessly integrated into the report completion process, eliminating the need for an additional step.

Start by reviewing all data points marked as ‘Incomplete’, flagged due to missing elements. The AI compares each answer against CSRD requirements and identifies gaps that need attention.

You can fill in missing elements manually or use Karomia’s AI assistant for an efficient process. Learn more about AI assistance.

After updates, refresh missing elements to verify that all required information has been included. Once a data point is complete, mark it as ‘Complete’ and finalize it by changing its status to ‘Validated’.

To streamline collaboration, you can assign tasks and track reporting progress within the platform. Discover Karomia’s collaboration.

Step 4: Get your CSRD report for publication

Once all data points are validated, you’re ready to generate your final report. In the Karomia platform, this is called the “Report for Publication”.

Karomia’s AI not only consolidates the data but also structures and formats it according to CSRD’s Sustainability Statement requirements, ensuring compliance while minimizing manual adjustments.

The Report for Publication compiles all disclosures (e.g., E1-1) into a clear, compliant report with structured text and tables, avoiding redundancies while maintaining accuracy.

This ensures no critical information is lost while keeping data close to its original wording, reducing the need for extensive revisions.
